If two sides of a right triangle are 8 and 7, what is the hypotenuse
____ [38]
To find the hypotenuse, simply use the pythagorean theorem. A^2+B^2=C^2
You know the two legs 7 and 8, so plug it in for A and B
7^2+8^2=C^2
49+64=C^2
113=C^2
C= approximately 10.63

Yaro buys a baseball cap for $9.50. He also buys a new baseball. Yaro speads $13.50 altogether.
VMariaS [17]

Answer:

13.5 = 9.5 + x

x=4

Step-by-step explanation:

In this problem, the price of the baseball cap, which is $9.50, and a baseball, whose price is unknown (and therefore must be the variable), total $13.50. So, to set up the equation add the two prices and set them equal to the total, 9.5+x=13.5.

Then, using the subtraction property of equality subtract 9.5 from both sides. This means x=4, so the baseball cost 4 dollars.
